Abstract
Изобретение относится к способу увеличения содержания оксида титана в шлаке, полученном в результате электропечной плавки титаномагнетита, причем способ включает подачу титаномагнетита, восстановителя и флюса в электропечь, плавление титаномагнетита, восстановителя и флюса в электропечи с образованием слоя, содержащего жидкий металл, и слоя, содержащего шлак, над слоем, содержащим жидкий металл, и извлечение жидкого металла и шлака по отдельности из электропечи. Флюс включает от 3 до 100 мас.% материала, содержащего оксид титана, такого как ильменит.
